One of the studs between the manifold and turbo completely disappeared in a later session that day. Since the track day, the car sounds like it has a screamer pipe when I get into boost. Hopefully things are still flat and the gasket is salvageable.

To try and figure out what is required to keep the MSM/SE hardware happy on track days, I am going to be a bit of a guinea pig and try things in stages. The first stage will be to add a flex pipe on the dump pipe and see if it makes any difference.

I'm using an aftermarket dump pipe that doesn't have the brace to the gearbox like the OE dump pipe. Not sure if this is worth adding back?
